Description
Astralpool terminal box set C63–C71 II 4405010154
The Astralpool terminal box set C63–C71 II 4405010154 is the original connection enclosure for selected C63 and C71 frame pool pump motors.
It houses the electrical terminals and cable glands, protecting the wiring from moisture, dust and accidental contact in demanding pool
plant rooms. With this complete terminal box set you can restore safe, compliant electrical connections on compatible motors supplied via
PoolParthub.com.
Function of the Astralpool terminal box set
The terminal box is the interface between the power supply and the motor windings. Inside the enclosure, the supply cable is securely
clamped, the conductors are fixed to the terminals and the protective earth is connected. The Astralpool terminal box set C63–C71 II
4405010154 provides a covered, insulated space for these connections, reducing the risk of loose wires, short circuits or accidental
touching of live parts during normal use and maintenance.
Design and construction
This terminal box set is built for use on C63 and C71 frame motors typically installed on residential pool pumps. The base, lid and
glands follow the original motor design so that cable entries, fixing points and gasket surfaces line up perfectly with the stator
housing. The materials are chosen for resistance to heat and to the slightly humid environment found in most filtration rooms.
- Original style terminal box body and cover for C63 and C71 frame motors.
- Internal space for terminal block and wiring according to motor connection diagram.
- Cable entry points designed for standard cable glands and flexible conduits.
- Cover fixing screws and sealing surfaces adapted to the original motor casting.
Compatibility and typical applications
The Astralpool terminal box set C63–C71 II 4405010154 is intended for pool pump motors that specify this reference in their exploded view
or spare parts list. It is typically used on small and medium residential circulation pumps where the motor operates many hours per day
and requires a robust, splash resistant connection enclosure.
- Suitable for C63 and C71 frame motors in the 0.5 to 1.25 horsepower range, where specified.
- Ideal when the original terminal box is cracked, missing or has damaged threads.
- Recommended during motor refurbishment to restore safe wiring conditions.
Always check the motor identification plate and the official parts diagram to confirm that reference 4405010154 is the correct terminal
box set for your model before ordering.
When to replace the terminal box
Even though it is outside the hydraulic section, the terminal box is exposed to heat, vibration and humidity. Over time, plastic can
become brittle, fixing points can break and cable entries can lose their sealing capability. A compromised enclosure presents a risk for
both electrical safety and long term motor reliability.
- Cracks in the lid or base that expose internal terminals.
- Broken or missing cover screws so the lid no longer closes firmly.
- Damaged or enlarged cable entries that no longer seal around the cable.
- Signs of corrosion or moisture inside the box around the terminal block.
Installation and wiring recommendations
Fitting the Astralpool terminal box set C63–C71 II 4405010154 is usually done during a motor change, bearing replacement or wiring
upgrade. All work on the electrical parts of the pump must be performed with the power supply fully isolated and, where required, by a
qualified electrician according to local regulations.
- Disconnect and lock out the power supply before opening the existing terminal box.
- Note or photograph the wiring configuration to replicate the correct connections.
- Remove the old box, clean the motor mounting surface and install the new base in its original position.
- Fit appropriate cable glands, route the supply cable and secure the conductors in the terminal block.
- Check earth continuity and tighten all terminals to the recommended torque.
- Close the lid carefully, ensuring the gasket is correctly seated and the cover screws are tightened evenly.
After reassembly, restore the power supply and perform functional checks, including correct motor rotation direction and verification
that the box remains dry and securely closed during operation.
Good practice for long term electrical safety
With a new Astralpool terminal box set C63–C71 II 4405010154 in place, a few simple habits help maintain safe, reliable connections over
many swimming seasons.
- Keep the technical room as dry and ventilated as possible to reduce condensation.
- Inspect the box periodically for signs of moisture, corrosion or mechanical damage.
- Check cable gland tightness and strain relief so the cable cannot pull on the terminals.
- Do not drill extra holes in the lid or base, as this can compromise protection.
Using the original Astralpool terminal box set C63–C71 II 4405010154 on compatible motors ensures that electrical connections remain
properly enclosed and supported, contributing to safe, dependable pool filtration in daily use.
